The IBM® Flex System™ EN6131 40Gb Ethernet Switch in conjunction with the EN6132 40Gb Ethernet Adapter offer the performance that you need to support clustered databases, parallel processing, transactional services, and high-performance embedded I/O applications, which reduces task completion time and lowers the cost per operation. This switch offers 14 internal and 18 external 40 Gb Ethernet ports that enable a non-blocking network design. It supports all Layer 2 functions so servers can communicate within the chassis without going to a Top-of-Rack (ToR) switch, which helps improve performance and latency.
